Great room acoustics
Great room acoustics are important and necessary to achieve optimal well-being in a
room. This applies at home, at work, at school or in restaurants. If room acoustics are
not optimal, speech comprehension is impaired, music is perceived vaguely, and a
large proportion of the sounds in the room will be perceived as noise. This will naturally

we all want is pleasant sound rather than noise. This is where it’s important to focus
on achieving the right reverberation time – how long sound takes to abate in a room.

The following are the various options in relation to achieving the recommended
reverberation time.
The optimal reverberation time depends on the purpose of the room. E.g., the optimal
reverberation time for a church is typically 6 seconds, while a living room in a private

Improve your acoustics
There are many ways to achieve improved room acoustics. Some of the common
methods are furniture, carpets, sofa cushions, heavy curtains etc. A good reverberation

time can therefore be difficult to achieve with minimalist decor, where the use of
carpets and furniture is sparse. Acoustic panels used as replacement for hard walls can
be a good solution.
In addition to being absorbent, acoustic panels also have a diffusing effect. Diffusers
can split the sound waves when the sound is reflected, making the sound more
evenly distributed throughout the room. This is perceived by the human ear as a more
